  • Hot Topics from the Annals of Surgery Ep. 2: Academic Surgery
    Sep 1 2025
    In the second episode of this new collaboration between BTK and Annals of surgery, we discuss another hot topic: academic surgery. Specifically, we discuss dedicated research time for residents and how surgical leaders think about building the academic surgery enterprise. This discussion was inspired by a couple of recent papers in Annals of Surgery that stirred up a lot of conversation on social media which can be found below.

  • I’ve Got 99 Problems, and a G Tube is One
    Aug 28 2025
    In this episode of Behind the Knife, Dr. Patrick Georgoff sits down with Dr. Keri Seymour and Dr. Joey Lew to tackle the complex world of gastrostomy tubes. What may seem like a routine and straightforward procedure is anything but—full of nuanced patient considerations, timing dilemmas, technical challenges, and potential complications that can turn a “simple” consult into a 2 a.m. call you won’t forget. From who truly needs a G tube and when to managing difficult post-op issues like dislodgement and buried bumper syndrome, this episode breaks down the practical, evidence-based approach every surgeon should know. Whether you’re managing stroke patients, trauma cases, or navigating the tricky administrative obstacles around enteral access, this episode will equip you with the insights and strategies to confidently dominate your G tube consults. Hosts: · Dr. Patrick Georgoff (Acute Care Surgeon, Duke University) · Dr. Keri Seymour (Minimally Invasive & Acute Care Surgeon, Duke Regional) · Dr. Joey Lew (Surgical Resident, BTK MIS Team) Learning Goals: By the end of this episode, listeners will be able to: · Understand the nuanced indications for gastrostomy tube (G tube) placement. · Learn which patients truly benefit from G tubes, and when enteral access is not appropriate or indicated. · Appreciate the importance of goals of care discussions, assessment of comorbidities, and decision-makers—especially in neurocritical and elderly populations. · Know evidence-based timing for gastrostomy tube placement in stroke, TBI, and other complex scenarios. · Understand guideline recommendations and the clinical reasoning behind trial periods of nasogastric feeding versus early G tube placement. · Describe technical approaches to G tube placement and how to tailor the method to patient anatomy and clinical context. · Solidify knowledge of when to choose endoscopic, laparoscopic, open, or interventional radiology-guided placement. · Recognize, manage, and strive to prevent common and serious complications of G tubes, including early and late dislodgement, buried bumper syndrome, infection, bleeding, and gastrocutaneous fistula. · Discuss perioperative considerations, including anticoagulation, patient stability, and post-procedural care. · Understand why routine suturing of the G tube or bumper is not recommended, and how administrative and facility factors can drive clinical decisions. · Gain practical pearls and quick decision trees to dominate G tube consults and troubleshooting, day or night.

  • Clinical Challenges in Vascular Surgery: Type B Aortic Dissections (TBAD)
    Aug 25 2025
    A silent danger lurks within the descending thoracic aorta. While most Type B aortic dissections are managed medically, up to half of these patients will either require life-saving surgery or die within just five years. So how do we separate those who will quietly recover from those on the edge of catastrophe? How do we protect the spinal cord, bowel, and limbs from the devastating consequences of malperfusion? Join the University of Michigan Department of Vascular Surgery as they tackle the high-stakes decisions behind managing this unpredictable disease—where timing is critical, interventions are evolving, and lives hang in the balance. Hosted by the University of Michigan Department of Vascular Surgery: · Robert Beaulieu, Program Director · Frank Davis, Assistant Professor of Surgery · Luciano Delbono, PGY-5 House Officer · Andrew Huang, PGY-4 House Officer · Carolyn Judge, PGY-2 House Officer Learning Objectives: 1. Discuss general approach to diagnosis and management of TBAD. 2. Identifying high-risk features in uncomplicated TBAD and understanding their role in determining the need for surgical management. 3. Review endovascular techniques for managing malperfusion of the limbs, viscera, and spinal cord and discuss associated decision making.

  • Journal Review in Endocrine Surgery: Parathyroidectomy for Fracture Risk
    Aug 18 2025
    Primary hyperparathyroidism is an underdiagnosed condition which leads to decreased bone mineral density, fracture, renal disease, among other symptoms that can decrease the quality of a patient’s life. Moreover, once diagnosed, only a small fraction of patients with the diease end up being offered surgery. Whether it is because of misunderstood indications and benefits of surgery, non-localization of disease, or various other reasons, we thought it was worthwhile to review relevant literature.

    Hosts: Dr. Becky Sippel is an endowed professor of surgery at Division Chief of endocrine surgery at University of Wisconsin Madison and she is the most recent past president of the AAES. She is an internationally recognized leader in the field of endocrine surgery. She has over 250 publications. She was the PI for a RCT which studies prophylactic central neck dissections which is a widely read and quoted study in endocrine surgery.

    Dr. Amanda Doubleday is a fellowship trained endocrine surgeon in private practice with an affiliation to UW Health. Her primary practice is with Waukesha Surgical Specialists in Waukesha WI.

    Dr. Simon Holoubek is a fellowship trained endocrine surgeons affiliated with UW Health. He works for UW Health with privileges at UW Madison and UW Northern Illinois. His clinical interests are aggressive variants of thyroid cancer, parathyroid autofluorescence, and nerve monitoring.

    Learning Objectives:
    1 Understand the natural history of primary hyperparathyroidism and how the disease process can affect bone mineral density.

    2 Learn about fracture risk associated with primary hyperparathyroidism.

    3 Learn about decreased fracture risk in patients with primary hyperparathyroidism who have parathyroidectomy compared to those who are observed.
